Mode of Operation
S 180 is an AC/DC current/
voltage metering relay. The 7
current and 13 voltage ranges
are selected by means of dif-
ferent code modules. AC/DC
metering and delay on oper-
ate/delay on release timer
functions are selected by DIP-
switch behind the code mod-
ule. Inversion of the output is
possible by interconnecting
pins 9 and 11. Latching and
extension of hysteresis are
possible by interconnecting or
adding a resistor between pins
8 and 9.
Example 1 - Delay on
operate, max. level detection
The relay operates when the
measured value exceeds set
point for more than the set
time. The relay releases when
the measured value drops
below set point less hyster-
esis. If the relay is latched it
remains ON once it has been
activated. Example 1 is a so-
called lower min. level guard
when the relay is not latched.
Example 2 - Delay on re- le-
ase, max. level detection
The relay operates when the
measured value exceeds set
point. The relay releases when
the measured value drops
below set point less hyster-
esis for more than the set
time. Example 2 is a so called
min. level guard when the re-
lay is not latched.
Example 3 - Delay on
release, min. level detection
The relay releases when the
measured value exceeds set
point for more than the set
time. The relay operates when
the measured value drops
below set point less hyster-
esis. If the relay is latched it
remains ON once it has been
activated. Example 3 is a so-
called max. level guard when
the relay is not latched.
Example 4 - Delay on
release, min. level detection
The relay releases when the
measured value exceeds set
point. The relay operates
when the measured value
drops below set point less hy-
steresis for more than the set
time. Example 4 is a so- cal-
led max. level guard when the
relay is not latched.
Latching can be released by
opening the contact between
pins 8 and 9 or by interrupting
supply voltage.
